Emerson 36C03-433 Natural Gas Valve with Taps LP,Eco 3/4 Inch 24V

The Emerson 36C03-433 is a compact 24V natural gas/LP gas control valve designed for use in forced-air heating systems with standing pilot ignition. It combines multiple functions into one unit, acting as a gas shut-off valve, pressure regulator, automatic pilot safety shut-off, and main gas valve. The 3/4-inch valve connects to standard piping with NPT threads and features two included 3/4-inch to 1/2-inch reducer bushings for additional installation flexibility. During operation, the valve opens quickly to allow gas flow upon receiving a 24V AC signal from the heating system's controls. An internal pressure regulator ensures consistent gas pressure delivery to the burner, while the automatic pilot safety shut-off immediately stops gas flow if the pilot flame extinguishes. This helps prevent dangerous gas leaks and improves overall heating system safety and efficiency. The Emerson 36C03-433 is a versatile replacement for many older gas control valves in residential and light commercial heating applications.
